refactor: simplify button styles across Svelte components

- Removed unnecessary 'btn-square' class from buttons in multiple components to streamline styling.
- Updated button elements in SolicitarFerias, editar, cadastro, and times pages for consistency and improved readability.
- Replaced SVG icons with Lucide icons for better visual consistency in the cadastro page.
- Cleaned up imports in the cadastro page to enhance code clarity.
